The
development of internet technologies has led to a growing internet population
and dramatically changed patterns of map use. Recently web map as a burgeoning
communication tool has developed rapidly for the advantages of operating simply
and immediately information distributing and sharing. But on the other hand,
web map has to be faced with some problems such as transmitting speed, spatial
data sharing, spatial information expressing and etc. W3C put forward the
standard for web vector graphics---SVG(Scalable Vector Graphics). As a new
technology based on XML, SVG had several key functions particularly suitable
for cartographic solutions such as coordinate system, layer management, high
level parameter on graphics elements, well designed interactive function and
etc.

This
paper concentrated on the methods of designing and implementing dynamic and
interactive web map of the campus of NanjingNormalUniversity
based on SVG. This paper expatiated the design methods of the interface,
layers, symbols and annotation of the map. We used Coreldraw software to build
a 2D map but with 3D feeling and transmit it to SVG. The paper also introduced
the developing methods of web map browsing, layers control, attribute querying
and etc. We also implemented some functions for user such as browsing the
ambient environment based on SVG Xlink and Quicktime, dynamic interaction,
dynamic animation of the campus bus, multimedia function. At last we discussed
the methods of web map distribute.
